Which statement accurately describes the membership of the League of the Five Nations?

• A. The Haudenosaunee Confederacy included four nations: Mohawk, Oneida, Onondaga, Cayuga.
• B. The League of Five Nations included Mohawk, Oneida, Onondaga, Cayuga, and Seneca, plus Tuscarora from the start.
• C. The League originally did not include Seneca.
• D. The League comprised Mohawk, Oneida, Onondaga, Cayuga, and Seneca; later joined by the Tuscarora.

Answer: (D)

The question is about how the Iroquois Confederacy grew over time. The group initially formed with four nations—Mohawk, Oneida, Onondaga, and Cayuga. The Seneca joined later, creating the Five Nations. The Tuscarora then joined after that, expanding the alliance to six nations. So the description that the League consisted of Mohawk, Oneida, Onondaga, Cayuga, and Seneca, with the Tuscarora joining afterward, matches the actual sequence. The other statements misstate either who was present at the start or when the Tuscarora joined.
